The Features and Functions of a Geothermal Heat Pump

One of the most unexpected things about a geothermal heating and cooling system is that it has so few moving parts. There’s just that much less that can go bad– that much less needing maintenance. And that in itself plays a huge role in slashing the overall energy costs of Southeast Missouri homeowners who’ve gone geothermal.

 

Of course, there are some moving parts in the system. Most of them are found in its most essential component, too: the geothermal heat pump.

This is the system’s workhorse. Its job is to transfer heat. And it transfers heat either from the ground into your house or from your house into the ground, depending on seasonal temperatures. As such, it’s a furnace and an air conditioner combined in one unobtrusive package.

How the heat pump transfers heat is with water or an antifreeze solution. This liquid circulates through pipe loops installed underground and attached to the heat pump, which is kept above ground. During heating season the liquid draws heat from the ground, the heat pump draws the warm liquid up into refrigerant coils, and the heat is then is circulated throughout a home by way of either a forced air or a hydronic system. During cooling season the process is reversed: the pump draws heat from your home and transfers it underground via those same buried loops. Oh, and as an added bonus, many geothermal systems also supply domestic hot water.

The basic distinction between a geothermal heat pump and a more familiar furnace is that a heat pump doesn’t ignite fuel to generate heat. Rather, it takes heat that’s already there and merely moves it around. That naturally makes it a much more efficient heating and cooling system. Keep this in mind, too: underground temperatures usually remain at around 50º F all year long. And that means? A geothermal heating and cooling system uses significantly less energy to cool your home than typical air conditioners.
